Gongzi Lan, surnamed Mi, surnamed Xiong (also known as Lan), is the youngest son, the younger brother of King Xiang of Chu. In the 30th year of Chu Huaiwang (299 BC), Zhao Haoqi, king of Qin, tricked Chu Huaiwang into Meng Hui, Qin (now Xianyang, Shaanxi). Zhao Sui, Qu Yuan and other ministers opposed Wang Huai's going, but Zilan strongly urged Wang Huai to go. After King Huai was detained, Xiang Wang acceded to the throne and was appointed Lingyin, holding the military and political power of Chu State.
